I COUPLER RELEASE EIGGING.

application; filedIDfecember 30,: Serial No. $48,355, it

" of uncoupling device shown in the patent to James R. Carmer, 79,9,4I6,dated Sept 12th,

1-915, and. like the. Carmer device my im-' proved release rigging maybe operated by means of the handor foot when a trainman is standing onthe cornerv step of the plat form without liability of being caughthetween the end sills of the car when taking slack, and, furthermoreenabling the trainmanv to use his signaling-lantern, or hand during theoperation of uncoupling and mmediately after the uncoupling operation.

, My improved rigging may be operated by hand the center or at theendofthe car end sill-:whenoccasion requires.

A further object in my invention is to increase the lifting power ofthis type ofrelease rigging which increase of power is desirable inconnection with the new standard type of coupler now in general use.accomplish these objects without interfering with the service movementsof the coupler;

and with these and other objects in view my invention consists of partsand combination of parts, as will be hereinafter more fully set forth. Iv

In the drawings':' I I Fig; 1. is a topplan view of a portion of the endstructure of a car, with my improved rigging mounted thereon.

Fig. 2. is a front elevation of a portion of the end structure of a carwith my improved rigging mounted thereon. i

Fig. 3. is a side elevation of the double fulcrum bracket.

Fig. 4. is a front elevation of Figure 3.

Fig. 5. is a detail perspective view of the end of the pin liftinglever.

The reference numeral 1 designates a portion of the end structure of acar, 2 a coupler and 3 a coupler look pin which are of standardconstruction.

The bracket for my improved, rigging consists of a base plate 4 which issuitably secured to the end structure of the carand 15 provided with thefulcrum members 5, 6,

the said U-shaped protuberance. vers are secured on'their fulcrums bymeans p'ositi'one d in different horizontal planes, the

fulcrum member '5, being longer than the are providedwitlrre'duced'screw' threaded fulcrum member 6." The fulcrum members I Ihas: its" outer portion permanently sagged downwardly so that the foot'or hand portion 10 is normally positioned below the plane of the underface. of the car end structure, whereby danger of the foot or hand of"the operator being caught between the e'ndsillsofthe adjacent I & ilimin d- T in r nd b ith sh fting lever 9,1is enlarged and provided withan opening through such enlargement through which the fulcrumfdprojects. The d ameter of the opening inthje inner end of i the shiftinglever 9' is gre'ater t'han thedi- 'aineter of the fulcrum 6' whereby thelever 9 is loosely mounted on the fulcrum 6 so that the lever will notbecome jammed onf its fulcrum due to any service movementsfltfhat may berequired of the lever; V For instance thelever may slide backwardf fa'ndforwardv on the fulcrum to accommodate the draft and butting actionofthe coupler;

To operate the lock pin 3 the outer end of the shifting lever 9 is moveddownwardly in a vertical plane by the hand or foot of the operator andas the lever 9 isseated in the U-shapedprotuberance of the lever l3 suchdownward movement of the shifting lever moves the pinlifting lever 13 onits pivot this causes the inner end thereof to be elevated therebylifting lock pin 3 and positioning said pin and its coupler in lock setposition.
